Hamegg is a frequent player in the Osamu Tezuka Star System, and a regular antagonist in various Astro Boy series. He usually appears as a shady circus ringleader, the second person to own and raise Astro, and often appears as a general criminal throughout the rest of the series.

Osamu Tezuka was inspired to create Hamegg from two sources, one being the villain of Milt Gross's He Done Her Wrong, and the Hungarian-German actor Peter Lorre. Hamegg has a very distinct round face, based on Lorre's, and a wide toothy grin, based on Gross's villain.

Most often, Hamegg is depicted as a lanky man in his 30s-40s, with a mustache and slicked-back black hair. On rare occasion he has been depicted with differently-coloured hair (dark green, Metropolis) or even as a different ethnicity (Jetter Mars).


Hamegg can be best described as shady and slimy. He is often scheming, or helping others pursue their schemes. His most well-known Star System roles are as a crooked circus owner or as a mob henchman. Hamegg is generally motivated towards crime by a love of money and power. Despite this, he is also cowardly and easily frightened. He may be comfortable pushing Astro around, but has been intimidated by Dr. Ochanomizu and Skunk.

He often appears as a criminal alongside Lamp, Marukabi Boon, and Skunk, but Hamegg is the most meek and skittish out of the group.

Hamegg, appearing under the name Mr. Cacciatore, is a secondary antagonist in the 1987 NOW! Comics series. He is a shady businessman and ringmaster who purchases Astro from Dr. Boynton. Cacciatore maintains aggressive control over Astro with a robot spider bomb called Bruno, and for the most part, neglects the upkeep of his other robots. When Cacciatore's circus burns down, he turns to organized crime, and acts as the middleman in orchestrating a robot siege on the Institute of Science.


1963 series

Hamegg first appears in the 1963 series, buying Astro from Dr. Tenma. He takes him into the circus as a main attraction. He is cruel towards Astro and easily frustrated with him, but regardless, Astro still saves Hamegg's life when the circus collapses and starts on fire. Ochanomizu meets Hamegg in the hospital, taking Astro away, much to Hamegg's dismay. In the English dub, he is named Mr. Cacciatore and given a heavy Italian accent.

From this point, Hamegg appears throughout the 1963 series as a part-time criminal or an odd-job worker, under various names. He is not a malevolent criminal, but tends to carry whips or guns.

Hamegg then ordered the big robot to punish mars by whipping him. Then a Clown Robot who met Mars before interfered, and was whipped as well. Mars managed to put a stop to the robot, though.
